- a lower guide roll 8 a band tension roll 9 and an upper guide roll 11 are provided. These rolls 8 , 9 and 11 are formed at their surfaces with grooves, respectively, in order to guide the casting band 7 more stably.
- the lower guide roll 8 is located just below the casting wheel 6 to come into contact with the casting wheel 6 while interposing the casting band 7 therebetween.
- the band tension roll 9 functions to adjust a tensile force applied to the casting band 7 while guiding the casting band 7 . That is, such a tensile force applied to the casting band 7 is adjusted by a tension adjustment cylinder 9 a of the band tension roll 9 , which is axially coupled to a bracket 9 b for fixing a rotating shaft of the band tension roll 9 .
- the apparatus of the present invention is further provided with a band press roll 10 .
- the band press roll 10 is installed just above the casing wheel 6 to apply a press force to the casting band 7 for allowing the casting band 7 circulating around the casting wheel 6 to come into close contact with the casting wheel 6 .
- the press force of the band press roll 10 is adjusted by a press force adjustment cylinder 10 a thereof, which is axially coupled to a bracket 10 b fixed at a rotating shaft of the band press roll 10 .
- the casting wheel 6 is provided above the rear side thereof with a plurality of gas injectors 12 arranged at regular distances, in addition to the cooling jacket 6 b contained inside the casting wheel 6 in a hermetic manner as stated above.
- a casting band thereof horizontally extends as a guide roll is disposed in parallel to an advancing direction of a casting material.
- the upper guide roll 11 and band tension roll 9 are installed above both sides of the casting wheel 6
- the lower guide roll 8 is installed below the casting wheel 6 .
- This arrangement of the guide rolls 8 and 11 and band tension roll 9 prevents the casting band 7 from interfering with the advancement of the solidified magnesium-alloy plate, thereby minimizing the generation of any defects due to the deformation of the casting material.
- FIG. 4 is an enlarged view illustrating ignition-suppression gas injection tubes as one component of the apparatus for manufacturing a magnesium-alloy plate and shapes using wheel-band continuous casting in accordance with the present invention.
- FIG. 4 shows a state wherein the molten magnesium-alloy, designated as reference numeral 14 , is guided into the recessed portion 6 a of the casting wheel 6 through the casting runner 4 and a molten magnesium-alloy injection plate 4 b , thereby being continuously cast while receiving the mixed gas from the ignition-suppression gas injection tubes 5 at the upper side thereof.
- the mixed gas consists of CO 2 and maximally 1 percent of SF 6 .
- the molten magnesium-alloy 14 guided into the casting wheel 6 is cooled and solidified by virtue of the cooling capability of the casting wheel 6 and the gas injectors 12 installed at the rear side of the casting band 7 for blowing cooling gas, thereby being continuously cast into a plate.
- AZ31(Mg—Al—Zn) material as a kind of processing magnesium-alloy was cut and inserted into the melting furnace 1 , thereby being converted to a molten state therein.
- the obtained molten magnesium-alloy was maintained at a temperature of 730 degrees for about 20 minutes for the stabilization thereof.
- the middle valve 2 a provided at the transfer runner 2 extending outward from the melting furnace 1 , the molten magnesium-alloy was transferred along the transfer runner 2 to be received in the heat insulation furnace 3 .
